BY W, ATTORNEY Patented Jan. 14, 1930 WILLIAM 'B. TUBBS, or LOS ANGELES, CALIFOR PERMANENT mun. WAVE non Application filed May 9, 1929. Serial No. 361,772.

This invention relates to hair curling apparatus and more especially to permanent wave making devices.

In the art of producing waves in hair dressing a switch or hank of the hair of the patron is twisted on a rod and this is en= veloped in a baker which is electrically heated. lVhen the apparatus is removed the released hair takes a wavy set; I

The usual form of rod is aplain-cylinder and when the hair is released from it the hank has a tendency to take a screw curl. It is an object of this invention to avoid this curling effect and to cause the hair to lie in smooth waves.

p Therefore, the invention consists of a rod tion as it or tube of generally cylindrical 'form whose surface is provided with shallow undulations of uniform pitch, which may be of helical form or of successive peripheral valleys.

Other objects, advantages and features of construction and mode of operation will be understood that modifications, variations and adaptations may be. resorted to within the spirit, scope and principle of the invenis hereinafter more directly claimed. I Figure 1 is a; sideelevation of the rod.

Figure 2 is an end view thereof.

- Figure 3 shows the application of the rod 7 to a hank of hair.

(li igure 4 is a side view of a helical groove ro The preferred form of the device consists of a metallic rod or tube 2 of about onequarter of an inch diameter reduced at the scalp end 3 which is provided with a diametrical slit 4 to receive a binding and tieing cord G;

At a suitable distance back from the, end 3 the rod is provided with peripheral groovesof shallow depth and about onequarter inch pitch preferably. The grooves are divided by ridges or beads in the form.

of truncated cones base to base; thus the ridges are more or less of of the grooves;

In Fig. 4 the grooves 5 are of helical form. In practice a hank of hair H is gathered and tied by cord C to the small end of the rod 2 and is then laid in a'helix along the rod, crossing from groove to groove as shown in Fig. 3, andagain fastened.

Should the helical groov'e rod '2 be used the hair is wrapped with a twist opposite to the pitch of the helix 5. i

' What is claimed is:

A device for use in permanent hair waving apparatus including a rod of generally cylindrical form and having shallow surface grooves in succession from near its scalp end; the grooves being formed between portions of truncated cone-like forms set baseto-base. V r
